This article maps out the crucial role and responsibilities for business in fighting poverty and acting responsibly in developing countries. It begins by proposing different ways to categorize the literature on corporate social responsibility (CSR) in developing countries. It then reviews the research which has been conducted at a global and regional level, before considering the main CSR drivers in developing countries. Finally, it proposes a model of CSR in developing countries, before concluding with a summary and recommendations for future research. What is clear from this article is that CSR in developing countries is a rich and fascinating area of enquiry, which is becoming ever more important in CSR theory and practice. And since it is profoundly under-researched, this enquiry also represents a tremendous opportunity for improving the knowledge and understanding about CSR.
